Strange battery issue.

[Dom_capper]

Hi.

I'm a bit stuck with a fault i think may be related to the battery. If the car is not running then the battery will very quickly run flat to the point where the car has to be bumped. When i say quickly, if i was to park up and leave just the hazards on for 5 mins the battery would be dead.
I've had the battery tested at halfords and was told (have the readout receipt if useful) the battery is fine and the alternator is charging it fine.

Has anyone got any ideas?

Thanks.

How old is the battery?

A battery can pass a load test but it still may not hold its charge.

I'm gonna say it needs a new battery mate

Battery is original as far as i'm aware. so 3ish years. Would it be worth sticking the battery from a friends car in and leaving the lights on for a while?

Ahh so we're not talking 1*2 here then mate?

It would be worth checking yeah, if it does the same then there's obviously something else at fault

No sorry. Mk3 1.2. Thanks mate. i'll give that a try.

Might just need a slow charge for a couple of days.

To be fair i commute from manchester to sheffield and back every weekend so plenty of long distance driving to keep it topped up. Would it still benefit from a slow charge?
